Worst-Case Morphs: a Theoretical and a Practical Approach. (arXiv:2111.15416v2 [cs.CV] UPDATED)

Face Recognition (FR) systems have been shown to be vulnerable to morphing
attacks. We examine exactly how challenging morphs can become. By showing a
worst-case construction in the embedding space of an FR system and using a
mapping from embedding space back to image space we generate images that show
that this theoretical upper bound can be approximated if the FR system is
known. The resulting morphs can also succesfully fool unseen FR systems and are
useful for exploring and …
